The Ladybugs Who Lunch
Help students learn about the diet of these hungry little beetles by creating restaurant-like “specials” menus using white chalk and black paper. Explain that a ladybug's favorite food is a tiny green bug called an aphid. In fact, an adult ladybug can eat 50 aphids in a day! Other ladybug treats include mites, leaves, mealybugs, nectar, pollen, and honeydew. Have students research the ladybug's diet further, then use their creativity to come up with a tasty menu!

"Spot the Dots" Graph
Build addition and multiplication skills with an easy-to-make math graph. Each student needs a circle made of red construction paper, a black crayon, and tape. Have students create ladybugs by drawing up to seven spots on their circles. Set up a graph like the one at right, and have students tape their bugs to the proper columns according to the number of spots. Invite them to add or multiply the spots in each column.

Ladybug Leaf Lore
Share the following fascinating ladybug facts with your students, and ask them to research even more.

• The U.S. has more than 450 types of ladybugs.

• A ladybug may fly 100 miles in search of food.

• In the winter, ladybugs hibernate under leaves.

• A ladybug can have 0 to 24 dots on its body.

• A ladybug sheds its skin four times in its life.



On a bulletin board, use brown paper to create a tree trunk and branches. Hand out green construction paper and guide the class through these steps: 1. Fold the paper in half and cut out a leaf shape.

2. Write a ladybug-related question on the front of the leaf. Flip the leaf over and write the answer on the underside. Draw a few “hibernating” ladybugs.

3. Staple the leaves to the branches at each leaf's top point. Have students visit the board and flip the leaves over to discover a variety of ladybug facts!

Insect Symmetry (Using the Reproducible)
Teach children to spot symmetrical and asymmetrical patterns with the Insect Symmetry Reproducible, below. First, review symmetry by drawing an X on the board. Draw a line vertically through the center of the X and explain that the two halves are symmetrical because they match, like a mirror image. Encourage students to look for other examples of symmetry, such as butterflies and faces. Share the Reproducible and ask students to cut out the ladybugs, then sort them into two groups — symmetrical and asymmetrical.
  • First the teacher will explain to students what symmetry is, and show examples in nature using photos along with educational symmetry video.
  • We are going to remove the Reproducible and instead let students practice symmetry using a variety of online interactive symmetry programs, including Make a Snowflake, Symmetry Artist, and Grid Activity.
  • After all students have finished practicing symmetry, they will use the IXL online Symmetry Assessment for 3rd grade to demonstrate what they learned about symmetry. We will require the students to complete 20 questions and then submit the assessment.

  • We decided that the original lesson plan included too many activities and was all over the place instead of focusing on one specific competency
  • We chose to focus solely on symmetry
